atented den. 19, 1932 LOUIS: W. HASSENBALL, F 00 Q wanna coonna Application aieanwemter a, race. serial No. acacia carbon dioxide may be employed as a. cooling medium.

One object of the invention is to provide a cooler equipped with an improved pocket or chamber to receive a block of compressed solid carbon dioxide, the pocket being so located in the cooler and so mounted that it opens through a side thereof and thereby permits a package of solid carbon dioxide to be passed into the pocket without removing the pocket or opening the cooler at its top.

Another object of the invention is to permit the pocket to be disconnected from a mounting -ring engaged through an opening in the side of the cooler if necessary without disturbing the ring and also to allow a cap to be engaged with the outer end of the ring or released therefrom Without disturbing the ring or pocket.

Another object of the invention is to provide a device of this character in which the solid carbon dioxide may be allowed to escape through one or more outlet openings in the cap or'pass upwardly through a coil disposed within the cooler and by cooling the coil assist in chilling the water.

Another object of the invention is to provide means for controlling passage of the carbon dioxide gas from the coil and allow this gas to either escape above or below the level of water in the cooler or pass outwardly through a discharge pipe extending through a wall of the cooler.

Another object of the invention is to allow the entire contents of the cooler to be car-- bonated if so desired or gas passing out of the cooler through a discharge pipe directed into a glass filled from the cooler and thereby cause the contents of the glass tobe carbonated.

The invention is illustrated in the accompanying drawings ,wherein Figure 1 is a vertical sectional view through the improved cooler,

The cooler consists of a body or container 1 which may be of any size and dimensions desired and this container has an open upper end normally closed by a head or cover 2 formed with an opening 3 through which the neck of an inverted water bottle may pass and about the margins of the opening is disposed a cushion or gasket 4 constituting a pad upon which the bottle rests. A crock or jar I 5 is disposed within the body 1 with its walls spaced from the walls of the body and if sodesired packing of heat insulating material may be placed between the walls of the crock and body. A draw-off spigot or faucet 6 extends through the walls of the body and crock at the front thereof and communicates with the interior of the crock at its bottom so that water may be drawn ofi from the crock. If so desired, the bottom of the crock may slope toward the outlet and thereby insure complete drainage of the crock when necessary and also prevent sediment from gathering in and the crock have their walls formed with alined openings 7 and 8 and about the opening 8 of the crock is formed a collar 9 WhlCh extends. outwardly from the wall of the crock and bears a ainst the wall of the body or casing about t e opening 7. An angular groove or 100 seat 10 is formed in the collar and at diametrically opposed points are formed notches 11 which extend from the groove and open through the wall of the crock. Therefore, a ring or sleeve 12 may be passed outwardly through the alined openings and after lugs 13 which project from opposite sides of the sleeve have passed through the notches 11 the sleeve may be turned, as shown in Figure 2, and the sleeve will be retained in place. Cement may be applied before the ring is passed through the openings or afterwards in order to form a water-tight joint and thereby prevent water from leaking out of the crock about this sleeve. This sleeve has its inner end portion projecting into the crock and this inner end of the sleeve is internally threaded for engagement by the threads formed about the open end of a cylindrical container or pocket 14 and about the open end portion of the container is formed an annular shoulder or ledge 15 against which is disposed a gasket 16. When the container is screwed into the inner end of the sleeve, the gasket is compressed between the shoulder and inner end of the sleeve thereby forming a watertight joint between the sleeve and container. The outer end of the sleeve is reduced and externally threaded so that a cap 17 may be screwed into place and a gasket 18 is provided about the sleeve so that when the cap is screwed tightly into place this gasket will be compressed and a tight joint formed. By an inspection of Figure 1, it will be seen that by removing the cap access may be had to the container or pocket 14. Therefore, a package 19 of compressed solid carbon dioxide may be passed into the container and when it has all evaporated the package may be removed through the open end of the container and a fresh package substituted. Lugs 20 project from the cap in order to permit it to be easily screwed tightly into place or removed and these lugs are perforated, as shown at 21, to provide passages through which the gas formed by the evaporating solid carbon dioxide may escape. By this arrangement the container will be chilled by the evaporating gas and water in the crock will be cooled. It will also be noted that when necessary a package from which the solid carbon dioxide has all evaporated may be easily removed and a filled package substituted without it being necessary to disturb the water bottle or raising the cover 2 of the body.

In Figure 3, there has been shown a modified construction. 1 Referring to this figure,

it will be seen that the sleeve 22 is shorter than the sleeve 12 and in addition to being provided with opposed lugs 23 for engagement in the seat 10 after being passed through the notches 24 is provided with an annular outstanding collar 25 against which fits a gasket 26 adapted to be compressed and against which is disposed a gasket 36.

form a tight joint when the cap 27 is screwed into place. This cap is provided with turning lugs 28, corresponding to the lugs 20, and through these lugs are formed gas passages 29. Adjacent its inner end the sleeve is formed with an internal shoulder 30 extending circumferentially of the sleeve against which bears a flange 31 formed about one end of a nipple 32 passed inwardly through the sleeve. The inner end portion of the nipple is externally threaded for engagement by the internally threaded open end of a pocket or container 33 and this pocket is provided at its free end with a narrow flange 34 to bear against the ledge 30 and in spaced relation to this flange with an outstanding collar 35 The inner end of the sleeve bears against this gasket when the container or pocket is screwed into engagement with the nipple and provides a tight joint. When this construction is used, a package of compressed solid carbon dioxide is inserted or an empty package removed in the same manner previously described.

In Figure 5, there has been shown a further modified construction. In this form of the invention, the container or pocket is engaged with a sleeve of a construction similar to that shown in Figure 1 and corresponding parts have been indicated by the same reference numerals. The outer end of the sleeve is closed by a removable cap 37 which may be provided with turning lugs if so desired but is not provided with openings for the escape of gas. A package of solid carbon dioxide disposed within the container will either fit loosely therein or have its sides perforated as well as one end and in order to allow the gas to escape, there has been provided an outlet neck 38 which projects upwardly from the container intermediate its ends. A coil 39 formed of metal tubing has one end connected with the outlet neck 88 and its coil extends vertically in the crock 5 with its upper end projecting above the crock. Therefore, the gas may pass upwardly through this coil and the coil will be chilled and assist in cooling the water. It should be further noted that the coil will be disposed about the neck of a water bottle disposed in an inverted position above the cover 2 with its neck extending through the opening of the cover into the crook and, therefore, the coil will not interfere with the neck of the bottle when the bottle is set in place. A two-way valve 40 is engaged with the upper end of the coil and this valve has the lower portion of its casing formed with a port 41 communicating with the coil and its side walls formed with ports 42 and 43 in which are engaged pipes 44 and 45. The valve plug 46 which is rotatably received in the casing of the valve is formed with an L-shaped passage 47, one end of which communicates with the port 41 and the other end of which is adapted to register with either the port 42 or the port 43 according to the position to which the plug is turned. The stem 48 of this valve projects upwardly through the top or cover 2 of the body and at its upper end carries a handle or turning lever 49 so that the valve may be easil adjusted without it being necessary to li t the cover. A gage strip 50 may be provided upon the cover in such position that the handle or lever moves along it and this strip may be marked to indicate proper positions for causing the passage 47 of the valve to register With the ports 42 and 43 or abutment pins to limit swinging movement of the lever may be provided upon the cover and suitably labeled to guide a person who wishes to adjust the valve. The pipe 45 passes outwardly through the side of the body so that when the valve is in the position shown in Figure 8 the gas may escape through this pipe and to the outer end of the pipe 45 is attached an elbow 51 extending downwardly and carrying a nipple 52 which fits tightly into one end of a flexible pipe 53. A nozzle 54 is attached to the other end of the pipe 53. By this arrangement gas passes through the plpe 53 and out through the nozzle 54 when the valve isin the position shown in Figure 8 and if a person drinking from the cooler desires to have water drawn from the cooler carbonated before drinking it, the nozzle may be thrust into a glass filled with water. Therefore, the escaping gas will pass upwardly through the water in the glass and cause the water to be carbonated.

When the valve plug is turned to such a position that its passage registers with the port 42, the gas will pass through the pipe 44 and into a pipe or elongated nozzle 55 which is connected with the pipe 44 by a short piece of flexible hose formed of rubber or any other suitable material. If the nozzle extends downwardly into the crock, as shown in Figure 5, the gas passing from this nozzle will move upwardly through the water in the crock and cause the entire contents of the crock to be carbonated but if the nozzle is swung upwardly to a substantially horizontal position in which its open end is disposed above the water level the gas will escape from the nozzle without passing through the water in the crock. This gas which escapes from the nozzle 55 passes upwardly into the upper portion of the body and may escape therefrom about the bottle or between the cover and the body portion of the cooler or if so desired outlet openings for this gas may be formed either in the cover or the walls of the cooler near its upper end. In order to allow the position of the pipe or nozzle 55 to be controlled, there has been provided an armi57 having a sleeve 58 at one end through which the pipe or nozzle passes. At its other end the arm is formed with a collar 58 engaged tightly about or formed integral with one end of a sleeve 59 which fits loosely about the pipe 45. This sleeve 59 is of such length that it extends through the wall of the cooler and'is held against sliding movement longitudinally by rings or collars 6O fixed upon the sleeve and bearing against inner and outer faces of the wall through which the sleeve and pipe 45 pass. A lever 61 has one end fixed tightly about the outer end of the sleeve 59 and this lever extends across a scale or strip 62 provided with lugs to limit swinging movement of the lever or lugs may be driven into the wall of the cooler to limit swinging movement of the lever. When the lever is disposed vertically, the arm 57 which extends in opposed parallel relation to the lever will extend downwardly into the crock and the nozzle 55 will be held in a depending position so that gas will pass upwardly through the water in the crock but by swinging the lever upwardly to a horizontal position the nozzle will be swung upwardly until its outlet end is disposed above the water and the gas will be allowed to escape without passing through the water in the crock. It will thus be seen that by this arrangement the water in the crock may be carbonated or left in its natural condition and by properly adjusting the valve plug 46 the gas may be allowed to pass outwardly through the pipe 53 and water drawn from the cooler into a glass individually carbonated. If so desired, the valve 40 and the elements connected therewith and their actuating handles or levers may be omitted and the gas permitted to pass directly from the upper end of the coil into the upper portion of thecooler. Instead of having the coupling 38 lead from the container intermediate the length thereof as shown in Figure 5, it may extend from its inner end as shown in Figures 9 and 10, and by referring to Figure 9 it will be seen that if so desired the tube forming the coil 39 may be coiled about the container as shown at 39. This will increase its cooling eifect.

Some manufacturers prefer to make blocks of solid carbon dioxide which are rectangular in cross section instead of circular and in order to accommodate a block 19' of frozen gas of this type, a container 63 which is rectangular in cross section has been shown in Figure 10. This container has an enlarged open end portion 64 formed with a marginal flange 65 which fits about the reduced end portion 66 of a sleeve 67 and bears against a washer 68 so that when the securing screws 69 are tightened a tight joint will be formed between the container and sleeve. The sleeve is also rectangular and of such length that it projects outwardly from the cooler and at its outer end is formed with inner marginal flanges 70 defining a seat for a gasket 71 which contacts with the cover 72 and forms a tightjoint between the cover and sleeve when the cover is applied. This cover is provided with a knob or handle 7 3 so that it may be easily grasped when set in place or removed and is securely held against the outer end of the sleeve by spring clips 7 4 secured at opposite sides of the sleeve and lips 7 5 extend inwardly from the cover to bear against the marginal flanges 68 and properly center the cover when in place.
